Elastic Beanstalk：字典更新序列元素#0 的长度为 1； 2 是必需的
Elastic Beanstalk: dictionary update sequence element #0 has length 1; 2 is required
我们有一个有效的 Elastic Beanstalk 环境，但在添加配置文件后，我们在部署期间开始出现此错误：
Error occurred during build: dictionary update sequence element #0 has length 1; 2 is required
配置文件如下所示：
# .ebextentions/seed.config
container_commands:
01_set_tenant_gateway:
command: rake db:seed:set_tenant_gateway
leader_only: true
env: our-env
日志给我们这个：

这里可能发生了什么？
1) env 键的语法：
env:
<variable name>: <variable value>
2) 此外，您需要将 command 括在引号中：
command: "<command to run>"
